OK how about this, This car is aerodynamic having been designed in a wind tunnel. Seats 4 people comfortably with upholstered seats, front seats can recline to make double beds. Steering column flattens out and is bent to attach to steering wheel making a safety 'net' in case of a collision. The body has 'break' points so in case of a collision, the sheet metal crumples, acting as a 'spring' absorbing the shock of the collision and NOT passing it on to the passenger compartment. both front and rear. Of course the car is front wheel drive with disc brakes up front but not just ordinary brakes, but full power brakes, the power coming from a 2000 PSI hydraulic pump. Brake 'pedal' is actually a large button, what is more it is positioned so that you can just slide your foot off of the gas pedal and on to the brake 'button' w/o lifting your foot. Brakes are inboard right along the trans axle and there are cooling ducts that bring air right onto the disc. The car had Oleopnumatic suspension ( air oil, suspensions was NOT regular springs, but sort of 4 super shock absorbers, spheres w/ sealed compressed nitrogen on top, a separator, and hydraulic fluid, with a special scintered disc between the sphere and the suspension column. All 4 suspension units were interconnected and front and rear anti sway bars also helped determine hight of the car (which you could adjust from 3 inches ground clearance up to 11 inches. car was self leveling, if you got 4 people and luggage into the car, car would of course sink down but then automatically adjust and raise itself to proper height. and of course you could adjust the height yourself with a flick of a lever . And while radial tires are not new, this car was designed from scratch for radial tires, but more important, the wheels were pivoted on the center, so if you got a flat, your car would not lose control. ( in fact this car was so balanced it could ride on 3 wheelers ). The car was also self jacking using the hydraulic suspension system. The Gas tank was under the rear seat where it was protected by a 'box' frame, the only way that gas tank could be punctured was if you were broadsided by a 18 wheeler ( and who would care at that point ). The headlights were connected to the steering ( which of course was power rack and pinion ) and the high beams followed the steering wheel, turning into the turn, illuminating what you were turning into, this would give you at least 2 or 3 seconds warning that there was something there, which often could be the difference between hitting something ( or someone ) and stopping in time. There are other features of this car but you can google it. And yes this car WAS in production, I'm talking about the 1968=69 Citroen DS 21, (in fact here is a picture of the 69 on mars ( did you know the French had a mars rover??? )
